Downward network traffic can be minimized by servicing set of users at network edge instead of service provider's data centers (e.g., multimedia and shared data) Content Delivery Networks (CDNs), and upward traffic can be minimized by processing and filtering raw data (e.g., sensors monitored data) and uploading the processed information to cloud.
This led me to specialise in enterprise applications development and, over the years, I've managed development teams on a range of high-profile projects, from digital TV content delivery through to public-facing, high traffic e-commerce sites.
The company uses Inktomi's Traffic Server and Content Delivery Suite to cache Web pages at its data centers.
Company CEO and founder Artur Bergman says they set out to build a better content delivery network by concentrating on the types of traffic that meet modern content requirements such as API traffic, mobile content and user generated content.
"We don't get much traffic from North Korea," says John Graham-Cumming of CloudFlare, a content delivery network – the equivalent of a regional parcel distribution centre, but for web traffic.
By the mid-2000s the vast majority of the Internet traffic was HTTP-based and content delivery networks (CDNs) were increasingly being used to ensure delivery of popular content to large audiences.
Faced with an ever increasing traffic demand, content providers and content delivery networks set large-scale caching infrastructures to distribute copies of the web content across multiple locations.
However, recent trends toward high data rate multimedia communication over WSNs demand traffic- and deadline-aware content delivery with minimum energy expenditure.
It got so bad that even Akamai, the huge content delivery network that handles 15-30% of all web traffic, had to tell Krebs that it couldn't continue to carry his blog because the attack was beginning to affect all its other customers.
The conventional-layered protocol design solutions are inefficient, as real-time content delivery requires interactions between multiple layers like application for traffic categorization, network for real-time delivery, and media access control (MAC) for prioritized medium access with minimum energy expenditure.
